Copy Maps upon Lead Conversion

Summary

Copy Map the same Lead field to both Account, Contact and Opportunity

Content

We have a Lead field that we need to pass to the newly created Account, Contact and Opportunity.  I see we can create a custom copy map to do this but couldn't find anything on whether it is possible to copy a custom Lead field over to all three newly created records so mapping to a custom Account field, custom Contact field and custom Opportunity field.

 

Thanks
